ISO 3166-1 alpha-2

From Wikipedia, the free encyclopedia
A map of Europe, with ISO 3166-1 alpha-2 codes in place of the full names of countries and other territories. 'Exceptional reservations' codes CQ, EU and UK are not shown.

ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard[1] published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO (the others being alpha-3 and numeric), and are used most prominently for the Internet's country code top-level domains (with a few exceptions). They are also used as country identifiers extending the postal code when appropriate within the international postal system for paper mail, and have replaced the previous one consisting one-letter codes. They were first included as part of the ISO 3166 standard in its first edition in 1974.

Uses and applications

[edit]

The ISO 3166-1 alpha-2 codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented.

Perfect implementations

[edit]

The ISO 3166-1 alpha-2 codes are used in the following standards:

Short name Long name Comment
ISO 3166-2 Country subdivision code[1]
ISO 3901 International Standard Recording Code (ISRC)[2]
ISO 4217 Currency code[3]
ISO 6166 International Securities Identifying Number (ISIN)[4]
ISO 9362 Bank Identifier Codes (BIC) Also known as SWIFT codes[5]
ISO 13616 International Bank Account Number (IBAN)[6]
ISO 15511 International Standard Identifier for Libraries and Related Organizations (ISIL)
UN/LOCODE United Nations Code for Trade and Transport Locations Implemented by the United Nations Economic Commission for Europe[7]

Imperfect implementations

[edit]

Starting in 1985, ISO 3166-1 alpha-2 codes have been used in the Domain Name System as country code top-level domains (ccTLDs). The Internet Assigned Numbers Authority currently assigns the ccTLDs mostly following the alpha-2 codes, but with a few exceptions.[8] For example, the United Kingdom, whose alpha-2 code is GB, uses .uk instead of .gb as its ccTLD, as UK is currently exceptionally reserved in ISO 3166-1 on the request of the United Kingdom.

The WIPO coding standard ST.3 is based on ISO 3166-1 alpha-2 codes, but includes a number of additional codes for international intellectual property organizations, which are currently reserved and not used at the present stage in ISO 3166-1.[9]

The European Commission generally uses ISO 3166-1 alpha-2 codes with two exceptions: EL (not GR) is used to represent Greece, and UK (not GB) is used to represent the United Kingdom.[10][11] This notwithstanding, the Official Journal of the European Communities specified that GR and GB be used to represent Greece and United Kingdom respectively.[12] For VAT administration purposes, the European Commission uses EL and GB for Greece and the United Kingdom respectively.

The United Nations uses a combination of ISO 3166-1 alpha-2 and alpha-3 codes, along with codes that pre-date the creation of ISO 3166, for international vehicle registration codes, which are codes used to identify the issuing country of a vehicle registration plate; some of these codes are currently indeterminately reserved in ISO 3166-1.[13]

IETF language tags (conforming to the BCP 47 standard track and maintained in an IANA registry) are also partially derived from ISO 3166-1 alpha-2 codes (for the region subtags). The full list of ISO 3166-1 codes assigned to countries and territories are usable as region subtags. Also, the "exceptionally reserved" alpha-2 codes defined in ISO 3166-1 (with the exception of UK) are also usable as region subtags for language tags. However, newer stability policies (agreed with ISO) have been implemented to avoid deleting subtags that have been withdrawn in ISO 3166-1; instead they are kept and aliased to the new preferred subtags, or kept as subtags grouping several countries. Some other region grouping subtags are derived from other standards. Under the newer stability policies, old assigned codes that have been withdrawn from ISO 3166-1 should no longer be reassigned to another country or territory (as has occurred in the past for "CS").

User-assigned code elements

[edit]

User-assigned code elements are codes at the disposal of users who need to add further names of countries, territories, or other geographical entities to their in-house application of ISO 3166-1, and the ISO 3166/MA will never use these codes in the updating process of the standard. The following alpha-2 codes can be user-assigned: AA, QM to QZ, XA to XZ, and ZZ.[21] For example:

Furthermore, the code element OO is designated as an escape code if the number of regular user-assigned code elements is not sufficient.[32]

Reserved code elements

[edit]

Reserved code elements are codes which have become obsolete, or are required in order to enable a particular user application of the standard but do not qualify for inclusion in ISO 3166-1. To avoid transitional application problems and to aid users who require specific additional code elements for the functioning of their coding systems, the ISO 3166/MA, when justified, reserves these codes which it undertakes not to use for other than specified purposes during a limited or indeterminate period of time.

The reserved alpha-2 codes are divided into the following three categories: exceptional reservations, transitional reservations, and indeterminate reservations.[21]

Exceptional reservations

[edit]

Exceptionally reserved code elements are codes reserved at the request of national ISO member bodies, governments and international organizations, which are required in order to support a particular application, as specified by the requesting body and limited to such use; any further use of such code elements is subject to approval by the ISO 3166/MA. The following alpha-2 codes are currently exceptionally reserved:

Code Area name or country name Current actual country ccTLD Notes
AC Ascension Island United Kingdom .ac Reserved on request of UPU for stamp issuing area
CP Clipperton Island France — Reserved on request of ITU for location of certain telecommunications installations
CQ Island of Sark United Kingdom — Reserved on request of the United Kingdom. Letters are derived from French name Sercq.
DG Diego Garcia United Kingdom — Reserved on request of ITU for location of certain telecommunications installations

Extended for any application needing to represent the name European Union in August 1999
EZ Eurozone multiple — Reserved on request of ISO 6166/RA for the European OTC derivatives within International securities identification numbering system (ISIN)
FX France, Metropolitan France — Reserved on request of France
Officially assigned before deleted from ISO 3166-1 (now assigned ISO 3166-3 code FXFR)
IC Canary Islands Spain — Reserved on request of WCO for area not covered by European Union Customs arrangements.
Code taken from name in Spanish: Islas Canarias
SU USSR multiple .su From June 2008; Transitionally reserved from September 1992
Officially assigned before deleted from ISO 3166-1 (now assigned ISO 3166-3 code SUHH)
Official name and previous ISO country name:[33] Union of Soviet Socialist Republics (common name: Soviet Union)
TA Tristan da Cunha United Kingdom — Reserved on request of UPU for stamp issuing area
UK United Kingdom United Kingdom .uk Reserved on request of the United Kingdom lest UK be used for any other country
Also used by the European Commission
United Kingdom is officially assigned the alpha-2 code GB
UN United Nations multiple — Reserved directly by ISO 3166/MA for the United Nations

The following alpha-2 codes were previously exceptionally reserved, but are now officially assigned:

Code Area name or country name Notes
AX Åland Islands Reserved on request of Finland
GG Guernsey Reserved on request of UPU for stamp issuing area
IM Isle of Man Reserved on request of UPU for stamp issuing area
JE Jersey Reserved on request of UPU for stamp issuing area

Transitional reservations

[edit]

Transitional reserved code elements are codes reserved after their deletion from ISO 3166-1. These codes may be used only during a transitional period of at least five years while new code elements that may have replaced them are taken into use. These codes may be reassigned by the ISO 3166/MA after the expiration of the transitional period. The following alpha-2 codes are currently transitionally reserved:

Code Formerly used country name Reserved from Reserved to ccTLD ISO 3166-3 Notes
AN Netherlands Antilles 2010-12 2060-12 .an ANHH Divided into BQ (Bonaire, Sint Eustatius and Saba), CW (Curaçao) and SX (Dutch part of Sint Maarten)

CS Originally Czechoslovakia, later Serbia and Montenegro 2006-09 2056-09 — CSHH
CSXX		 Code taken from name in Serbian: Srbija i Crna Gora, for Serbia and Montenegro, which however is now divided into Montenegro (ME) and Serbia (RS).
(Though reserved, the ccTLD .cs was never actually assigned to Serbia and Montenegro; the ccTLD of Serbia and Montenegro was .yu, as that formerly unified country's name, and that of its larger predecessor, had previously been Yugoslavia.)

Indeterminate reservations

[edit]

Indeterminately reserved code elements are reserved for use in a particular way, usually due to their presence in other coding systems. For example, several codes are reserved because they are used for international intellectual property organizations in WIPO Standard ST.3. The following alpha-2 codes are currently indeterminately reserved:

However, EA was already exceptionally reserved by the ISO 3166/MA to represent Ceuta and Melilla for customs purposes. The ISO 3166/MA proposed in 1995 that EV be used by WIPO to represent the Eurasian Patent Organization; however, this request was not honoured by WIPO.[35]
